Engine #2 has slightly more hours than the airframe - It's obviously a replaced engine.
26,466.08 hours is by no means high time, and anyway hours mean very little in engine maintenance. The reason? There are two typical limitations that will require an engine swap: operating cycles (= number of flights), and performance deterioration (can't deliver hot day performance within EGT limits). Of course FOD or other physical damage can do an engine in.
I don't know exactly what the current on-wing time record is before removal, but 20 years ago turbofan engines were regularly exceeding 20,000 hours, with far greater reliability than recips at 2000-3000 hour TBO's.
